This invention relates to new and useful improvements and structuralrenements in windowsfand the principal object of the invention is toprovide eiiicient and conveniently controlled ventilation.

This object is achieved by the provision of the instant window structure`which includes lwhat may be called an articulated sash unit consistingof several panels swingable on horizontal axes, and an important featureof the invention resides in the provision of individually adjustablemeans for retaining the several panels in an open or partially openposition.

`Another feature of the invention resides in the structural arrangementof the panels whereby they maybe folded one upon another if so desired,and a still further feature of the invention involves theV provision ofmeans for eiectively sealing the joints between contiguous edges of thesash panels when closed, thus safeguarding against the Vpassage ofweather through the closed window.

Y .l `Some of the advantages of the invention reside Figure l is aninside elevationalvlew ofthe inventon; a Figure 2 is a crosssectional'view; taken substantially in 4the plane of the line 2-2` inFigure 1; l Y Figure V3 is a group perspective View showing portions ofthe window frametogether with top and intermediate sash panels;

Like characters of reference are employed to designate like parts in thespecication and throughout the several views.

Referring now to the accompanying drawings in detail, more particularlyto Figures 1-5 inclusively, the invention consists `of a windowstructure designated generally by the reference character Hl, the sameembodying a rectangular frame l2 including a pair of spaced parallelside members I4 and a bottom member I6, this frame being adapted toaccommodate an articulated sash unit designated generally by thereference character IB.

' The sash unit i8 consists of a plurality: of con, tiguous panels whichextend transversely of the window opening, these panels beingdesignated, for purposes of convenient identication, as the top panel20, theintermediate panel 22 and'a bottom panel 24. Y

The side edges of the top panel 2d and intere mediate panel 22 arerecessed adjacent the con'- tiguous edges of the two panels toreceivesets of plates25, 28 respectively, these plates being secured in theirrecesses by suitable screws 3l] and each plate lbeing provided with alaterally projectingstud, namely, the stud 32 on the plate 25 and thestud- 36. on the plate 2S. The studs 3 2, 3d` are rotatable inrespective apertures 3B, 38 provided in flat mounting plates 40, thelatter, in turn, being secured. by thescrews 42 in suit-l able recesseswith which the side members I4 of the frame l2`are formed (see Figures 1and 3).

It will be apparent from the'foregolng that the*4 top panel 2n isswingable from its vertical closed position in the frame `I2 to an openposition ile! l-ustrated by the phantom line 44 in Figure 2, while theintermediate panel 22 is similarly swings able to an open positionillustrated by the phantom line 46. Y n

A suitable latch 48 (seeFigure 1) may be provided on the upper edgeportion of the top panel 2|!V for retaining this panel in its clos-edposition, and a length of chain .50, or the like, may be secured to theframe and to the top member 20 for the purpose' ofvrestricting theopening movement of the latter, as will be clearly apparent;

The 'side members'lof the frame I2 areprovided with vertically extendinggrooves 52 and a plurality of vertically `spaced keeperpinsldfextend'transvers-elyof these' grooves, as, is brest shown infFisurejl. A. pairciY keeperar'xs, 56` arie, pivot'ed as at 58' tothe side edge's'oftheintermediate panel 22, these arms being engageable selectively with thekeeper pins 54 for the purpose of adjustably retaining the panel 22 inits open position, independently of the top panel 2li. When the panel 22is closed, the arms 5S are received in suitable recesses Sil provided inthe side edges of the panel 22, and it is to be noted that the keeperarms 5S may be adjusted on the pins 54 in such manner that the panel 22is supported in a substantially horizontal position, thus facilitatinglowering of the top panel 2B to a superimposed position on the panel 22after disconnecting the chain 58.

As is best shown in Figure 2, a weatherstrip 62 is provided at the loweredge of the panel 28 to cover the contig-nous edges of the panels 28,22, which are rounded or arcuated as at Sii so that inward opening ofthe panels is facilitated but the weather is effectively excluded frompassing through the window when closed.

The bottom panel 2d is provided in the sides thereof adjacent its upperedge with suitablerecesses to accommodate portions of fiat links 68which are pivoted by suitable screws 5S to the panel 2t and extendupwardly therefrom, their upper portions, in turn, being formed withslots 'I0 to accommodate additional screws 'l2 whereby these links andthe panel 24 are connected to the lower edge portion of the intermediatepanel22.

It will be apparent from the foregoing that when the intermediate panel22 is opened, the links 66 will cause the bottom panel 24 to be openedconcurrently, and means are provided for preventing the bottom panelfrom swinging freely when in its open position, these means consistingof a pair of hooks 'lll which are secured as at 'It to the lower edgeportion of the bottom panel 24 and are engageable selectively with theaforementioned keeper pins 58 when the bottom panel is in its openposition, as indicated at 28 in Figure` 2. When the bottom panel isclosed, the hooks 14- are simply received in suitable recesses 8Bprovided in the bottom member I6 of the frame I2.

In order to safeguard against the passage of Weather through the closedwindow, the contiguous edges of the panel 22, 2li are ccmpleinentarilybeveled as indicated at 82 in Figure 2, and it should be explained thatthe purpose of the slots in the links 6B accommodating the screws 'i2 isto enable these complementarily beveled, contiguous edges of the panels22, 24 to be spread apart when the panels are opened, after which thebottom panel 2li may beswung upwardly to a ,superimposed position on theintermediate panel 22, as indicated by the phantom line 84 in Figure 2.Needless to say, this arrangement is employed when it is not desired tosecure the bottom panel 24 by engaging the hooks 'M with the keeper pins5s.

It will be apparent from the foregoing that the several panels of thesash unit may be quickly, easily and conveniently adjusted so as toproperly control ventilation through the window opening. Moreover, sincethe sash panels are swingable or openable inwardly, cleaning thereof isgreatly facilitated. If desired, co-acting latch members 86. 88 may beprovided on the bottom panel 2 and one of the frame-members i4respectively, these latch members facilitating locking of the bottompanel 24 to prevent its opening, and since the intermediate panel 22cannot be opened without opening the bottom panel 24, the latch membersv86, 88 effectively function to prevent unde- 4 sired opening of both theintermediate and the bottom panel.

A suitable screen may be provided in the frame I2 on the outside of thesash unit for obvious reasons.

Finally, it should be understood that the panels 20, 22, 24 consist ofsuitable perimetric frames equipped with transparent panes, inaccordance with conventional practice.

Referring now to the accompanying Figures 'I and 8, these figuresillustrate a modified embodiment of the invention designated generallyby the reference character |03, the same being similar to the embodimentalready described and consisting of a frame |02 provided with anarticulated sash unit |04.

However, this sash unit, rather than consisting of only three panels,consists of four panels. namely, the top panel |85, the upperintermediate panel IUS, the lower intermediate panel Il and the bottompanel H2. The structural arrangement and mounting of the panels |06 and|98 is similar to that of the aforementioned panels 29, 22, but thebottom panel |I2, rather than being connected to the panel |08, isconnected by the links H4 to the lower edge portion of the lowerintermediate panel H8, the upper edge portion of which, in turn, isconnected to the lower edge of the upper intermediate panel i 88 bymeans of a suitable hinge I6.

The side members of the frame |82 are again provided with verticalgrooves II8 and vertically spaced keeper pins |20, while the panels |08,II2 are equipped with the respective arms and hooks |22, |213 which areengageable independently and selectively with the pins I20.for thepurpose of adjustably retaining the several panels in their openposition. However, it is to be noted that by virtueof the hinge |I6 andlinks II4, the panels I I0, I I2 may be folded in a superimposedrelation on the op-en panel |08, as shown in Fig-ure 8.

The contiguous edges of the panels |08, I I0 and the contiguous edges ofthe panels Ill), II2 are complementarily beveled as indicated at |26,|28 respectively, while contiguous edge portions of the panels |86, |08are rounded or arcuated as at |28.

It is believed that the advantages and use of the invention will beclearly apparent from the foregoing disclosure and accordingly, furtherdescription at this point is deemed unnecessary.

While in the -foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the sprit and scope of theinvention as claimed.
